Description

Technical Field

[0001] This utility model relates to the field of sampling forceps technology, and in particular to a disposable live sampling forceps with hemostasis function. Background Technology

[0002] In the medical field, in vivo sampling is a common diagnostic method used to obtain samples of diseased tissue for pathological analysis. While traditional in vivo sampling forceps can effectively cut and extract tissue samples, bleeding is often a problem during the sampling process. This not only increases the risks of the procedure but may also affect the subsequent pathological analysis results. Furthermore, postoperative hemostasis usually requires additional time and steps, prolonging the operation, increasing patient suffering, and raising surgical costs.

[0003] Existing solutions include using a separate electrocoagulation device for hemostasis, but this requires additional equipment and procedures, increasing surgical complexity and physician workload. Therefore, a disposable live sampling forceps with hemostasis function is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a disposable live sampling forceps with hemostasis function to solve the problems in the background art.

[0005] In view of this, the present invention provides a disposable live sampling forceps with hemostasis function, comprising:

[0006] A handle assembly, wherein the handle assembly has two electrode plates that do not make direct contact;

[0007] The wire assembly includes a wire cable extending from the slider;

[0008] The clamp head assembly is connected to the wire assembly, and the opening and closing action is achieved by the movement of the wire cable;

[0009] When the slider on the handle assembly moves to one side, it drives the steel wire cable to move, thereby closing the clamp head;

[0010] During the closing process of the pliers assembly, the steel wire cable will contact the circuit connection between two non-directly contacting electrode plates, which is used to energize the pliers assembly to produce a hemostatic effect.

[0011] Optionally, the two non-contacting electrode plates include a positive electrode and a negative electrode, both of which are fixedly mounted on the handle assembly to ensure that when the slider moves to a preset position, the wire cable can trigger the circuit connection between the two electrode plates.

[0012] Optionally, the extension of the steel wire cable is provided with a conductive material, which forms a closed circuit with the two non-directly contacting electrode plates on the handle when the clamp assembly is closed.

[0013] Optionally, the clamp assembly is made of a material capable of withstanding a certain current so as to generate a thermal effect after being energized, thereby achieving the purpose of local hemostasis.

[0014] Optionally, the electrode plates of the positive and negative electrodes and the conductive parts of the steel wire cable are all made of biocompatible materials to ensure safety during use.

[0015] Optionally, a wristband is fixedly connected to one end of the handle assembly.

[0016] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages:

[0017] 1. This utility model discloses a disposable live sampling forceps with hemostasis function. By integrating electrocoagulation hemostasis into the forceps, it achieves simultaneous hemostasis during the sampling process. This not only reduces surgical time and steps but also improves surgical safety and efficiency. The surgeon only needs to operate one device to complete sampling and hemostasis, eliminating the need to switch between different devices, simplifying the surgical procedure and reducing its complexity. Real-time electrocoagulation hemostasis effectively prevents bleeding during and after sampling, reducing complications caused by bleeding and improving surgical safety.

[0018] 2. The present invention provides a disposable live sampling forceps with hemostasis function, which reduces surgical time and steps, shortens the time patients spend on the operating table, and reduces patients' pain and psychological stress.

However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0025] The following describes in detail, with reference to the accompanying drawings, a disposable live sampling forceps with hemostasis function according to an embodiment of the present invention.

[0026] Example

[0027] For easier understanding, please refer to Figures 1 to 2 An embodiment of a disposable live sampling forceps with hemostatic function provided by this utility model includes:

[0028] Handle assembly 1, wherein the handle assembly 1 is provided with two electrode plates that do not directly contact each other;

[0029] The wire assembly 2 includes a wire cable 21 extending from the slider 15;

[0030] The clamp head assembly 3 is connected to the wire assembly 2, and the opening and closing action is achieved by the movement of the wire cable 21;

[0031] When the slider 15 on the handle assembly 1 moves to one side, it drives the steel wire cable 21 to move, thereby closing the clamp head;

[0032] During the closing process of the clamp assembly 3, the steel wire cable 21 will contact the circuit connection between two non-directly contacting electrode plates, so as to energize the clamp assembly 3 and produce a hemostatic effect.

[0033] In some embodiments, the two non-contacting electrode plates include a positive electrode 11 and a negative electrode 12, both of which are fixedly mounted on the handle assembly 1, ensuring that when the slider 15 moves to a preset position, the wire cable 21 can trigger the circuit connection between the two electrode plates. The electrode plates of the positive and negative electrodes 11 and the conductive parts of the wire cable 21 are all made of biocompatible materials to ensure safe use.

[0034] It should be noted that the handle assembly 1 consists of two interlocking handles, one of which is fixed and the other is movable. Inside each handle are two electrode plates, a positive electrode 11 and a negative electrode 12, which are kept at a certain distance to avoid direct contact. The electrode plates are typically made of materials with good conductivity and biocompatibility, such as copper or stainless steel.

[0035] The slider 15 is mounted on the outside of the handle assembly 1 and its position can be changed by pushing it with a finger. A steel wire cable 21 is connected inside the slider 15, and the steel wire cable 21 moves with the slider 15.

[0036] The steel wire cable 21 is made of high-strength, corrosion-resistant stainless steel to ensure good mechanical properties even under repeated bending and stretching. The end of the steel wire cable 21 is connected to the clamp assembly 3, while its front end passes through the slider 15 and has a section of conductive material, such as silver or gold plating, at an appropriate position to form an electrical connection.

[0037] The forceps assembly 3 is configured with two opposing jaws, each with a sharp tip suitable for cutting and grasping tissue. A conductive coil is embedded inside the jaws; when current passes through, the coil heats up, raising the temperature of the jaws and achieving electrocoagulation hemostasis.

[0038] In some embodiments, the extension portion of the wire cable 21 is provided with a conductive material, which forms a closed circuit with the two non-directly contacting electrode plates on the handle when the clamp assembly 3 is closed.

[0039] It should be noted that conductive materials are preferably plated with silver or gold to form electrical connections.

[0040] In some embodiments, the clamp assembly 3 is made of a material capable of withstanding a certain current so as to generate a thermal effect after being energized, thereby achieving the purpose of local hemostasis.

[0041] It should be noted that the pliers assembly 3 is made of high-temperature and corrosion-resistant metal materials, such as stainless steel or titanium alloy. These materials can withstand the heat generated by high-temperature current and have good biocompatibility.

[0042] In some embodiments, a wristband 16 is fixedly connected to one end of the handle assembly 1.

[0043] It should be noted that the wristband 16 is located at one end of the handle assembly 1 and is used to increase the stability of the doctor's grip and reduce operational errors. The inside of the wristband 16 can be padded as needed to improve comfort.

[0044] Working principle: The handle assembly 1 contains two electrode plates, a positive electrode 11 and a negative electrode 12. A wristband 16 is fixed to one end of the handle assembly 1 to increase operational stability.

[0045] The wire assembly 2 includes a movable slider 15 and a wire cable 21 extending from the slider 15, the front end of which is provided with a conductive material.

[0046] The clamp head assembly 3, connected to the wire assembly 2, consists of two opposing jaws. Conductive coils are embedded inside the jaws, capable of withstanding current and generating heat. Check the equipment for damage and ensure the power connection is correct. Place the wristband 16 on your wrist to ensure stable operation.

[0047] The tissue area to be sampled is accurately located using an endoscope or other auxiliary tools.

[0048] Gently push slider 15 to allow the wire cable 21 to slowly bring the clamp head assembly 3 closer to the target tissue. Continue pushing slider 15 to close the two jaws of clamp head assembly 3 and clamp the target tissue. When slider 15 moves to the preset position, the conductive material at the front end of wire cable 21 contacts the positive terminal 11 and negative terminal 12 inside handle assembly 1, forming a closed circuit.

[0049] Current flows through the conductive coil, generating heat and raising the temperature of the grippers to electrocoagulate and stop bleeding in the clamped tissue. After confirming the hemostasis effect, the slider 15 is released, the grippers of the forceps assembly 3 open, and the sampled tissue is carefully removed.

[0050] After use, thoroughly clean and disinfect the equipment according to medical procedures for future use.

[0051] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
